GUN TRAIL.

Application filed September 20, 1923; Serial N10. 663,907.

7 (FILED UNDER THE ACT OF MARCH 8 1883, 22 STAT. L, 625.)

T 0 all whom it may concern:

Be it known that I, HARRY C. ZIMMER- MAN, a citizen of the United States, and a resident of Washington, District of Columbia, have invented an Improvement in Gun Trails, of which the following is a specification.

The invention described herein may be used by the Government, or any of its officers or employees in prosecution of work for the Government, or by any other person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

The present invention relates to gun trails.

The primary object of my invention is the provision of a trail member which may be constructed from sheet metal members readily bent to shape and easily secured together.

A further object is the provision of a trail member which may be cheaply constructed and which when assembled may have requisite strength.

With the foregoing and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompanying drawing wherein:

Fig. 1 is a view in rear elevation with parts broken away of a gun carriage provided with a trail such as forms the sub j ect of this invention.

Fig. 2 is a section through a trail member; and

Fig. 3 is a sectional view showing a modified form of my invention.

Referring to the drawing by numerals of reference:

I have shown a gun carriage 5 of any suitable structure to which is attached a trail member 10 formed of a pair of end plates 11 and 12, preferably of channel form and made of sheet metal. These end plates 11 and 12 are constructed with webs 13 and 14, respectively, and with spaced flanges or legs 15 and 16 bent up from the respective webs.

The flanges or legs15 and 16 may be made of any desired length. In that embodiment of my invention shown in Fig. 1 the flanges 15 of the plate 11 are of substantially greater length than the flanges 16 of the plate 12; in the modification shown in Fig. 2 however, the flanges 15 are of the same length as the flanges 16, the plates being identical in structure. In the latter form side plates 17 are attached to the flanges 15 to give the trail arm the desired depth. The web 14 is adapted to bridge the space between the flanges 15 of the member 11 or between the plates 17 in the modified form; and the respective flanges 15 and 16, or in the modified form, the flanges 15 and 16 and plates 17 are adapted to extend continuously.

With a structure of the type described the web and projecting flanges of the inner member 12 are adapted to strengthen the flanges 15 or the lates 17 attached to the other member 11 so that the trail Will be able to withstand any ordinary pressure Or disrupting force. The corresponding flanges of the members 11 and 12 in the form shown in Fig. 1 are connected together by rivets 18 or if desired by bolts by welding or in any other well known manner.

In the modification shown in Fig. 2 the members or plates 17 are attached to the corresponding flanges of the channel plates 11 and 12 by riveting, welding, bolting or in any other well-known manner.

With either of the forms of my invention described the trail member may be constructed cheaply and at the same time be readily assembled and when assembled will have the requisite strength.

While I havedescribed my trail members as formed from channel plates it is obvious that any other type of plate may be employed without altering the function of the invention.

My invention is readily applicable to the arms of a single trail member or to the trail members of a split trail.

I claim:

1. In a gun carriage, a hollow trail arm embodying spaced end plates of identical structure, each formed with a web and a pair of spaced legs, the corresponding legs of each plate extending in substantially the same direction, and spaced side plates attached to the outer faces of corresponding legs of the end plates for connecting the end plates together.

2. In a gun carriage, a hollow trail arm embodying spaced end plates of identical structure, each formed with a pair of legs, the corresponding legs of each plate extending in substantially the same direction and spaced side plates attached to the outer faces of corresponding legs of the end plates for connecting the end plates together.

3. In a gun carriage, a hollow trail arm embodying spaced end plates of identical structure, each formed with a pair of legs and spaced side plates attached to the outer faces of corresponding legs of the end plates for connecting the end plates together.

4:. In a gun carriage, a hollow trail arm embodying spaced end plates, each formed with a web and a pair of spaced legs, and

spaced side plates, each attached to the outer faces of correspondin legs of the end plates for connecting the en plates together.

5. In a gun carriage, a hollow trail arm embodying spaced end plates, each formed with a web and a pair of spaced legs and spaced side plates connecting corresponding legs of the end plates together.

6. In a gun carriage, a hollow trail arm embodying end plates of identical structure, each formed with a pair of legs, and means connecting the corresponding legs of the end plates together. 7 V

7. In a gun carriage, a hollow trail arm embodying spaced end plates of identical structure, each formed with a pair of legs, and means connectlng the end plates together.
